Viewing Writing as Video: Optical Flow based Multi-Modal Handwritten Mathematical Expression Recognition

Hanbo Cheng, Jun Du, Pengfei Hu, Jiefeng Ma, Zhenrong Zhang, Mobai Xue

ICASSP 2024accepted

Handwritten Mathematical Expression Recognition (HMER) forms a crucial task in the domain of document intelligence. It encompasses online and offline modalities, which utilize the trajectory sequence and static image as input, respectively. It is intuitive to utilize both online and offline modaliti…

Perceiving Stroke-Semantic Context: Hierarchical Contrastive Learning for Robust Scene Text Recognition

Hao Liu, Bin Wang, Zhimin Bao, Mobai Xue, Sheng Kang, Deqiang Jiang +2

AAAI 2022technical

We introduce Perceiving Stroke-Semantic Context (PerSec), a new approach to self-supervised representation learning tailored for Scene Text Recognition (STR) task. Considering scene text images carry both visual and semantic properties, we equip our PerSec with dual context perceivers which can cont…
